'Hot' fix 1.0.2

Hello pizza delivery enthusiasts!

First of all, happy Cosmonautics day! To celebrate it we've prepared a small update for you.

Patchnotes (1.0.2):

• Sputnik Λ has been added in levels 2 - 7 and 9. A new type of Sputnik that will not kill you, but instead vaccinate your character and make it known to everyone else!
• A hidden achievement has been added. Interact with a Sputnik Λ to see what happens.
• Steam Achievements. Some achievements were not being unlocked, this is now fixed (we hope).
• Sound Control in Options. The slider position is now remembered. Also the default value is no longer a 100%.
• Various platform position fixes throughout the first chapter.

Thank you and happy delivering!
